Software for analyzing the probability of collisions of birds with rotors of wind electrical installations

Abstract

The program "Birds" has been developed for analyzing the risks of bird collisions with turbines of wind power stations. The mathematical model of the program is based on the recommendations of the Scottish Natural Heritage Foundation. The source database contains the necessary information in relation to the operating conditions of the wind farm "Primorsk-1", which is supposed to be built on the coast of the Azov Sea in the Zaporizhia region. If necessary, the user can enter his own values and get results on the interaction of birds with wind turbine rotors on the following indicators: bird flight time through the rotor space, probability of collision of one individual with the turbine, depending on its flight characteristics and parameters of the wind electrical installation, number of bird collisions at a given time interval. The program was tested using the example of calculating the number of collisions of birds with rotors during one year of operation of the Primorsk-1 wind park. It is shown that the probability of a collision of one bird with the rotor depends little on its geometric dimensions and is in the range of 11-15%. The total number of collisions of all birds on the territory of the wind farm will be 6,4 birds, which corresponds to 0.25 individuals per turbine. Most of this amount (about 4.8) refers to two species: Merops apiaster and Larus ridibundus.
